Embodiment 1

[0022] A processing method for improving the oil yield of peony for oil, comprising the steps of:

[0023] 1) Microwave treatment

[0024] Pick the fully mature purple spot peony fruits that have been removed from the soil, dry them in a dry and ventilated place for 4 days, beat the fruits to make the peony seeds fall off naturally, collect the fallen peony seeds, crush them into peony seed powder for oil with a particle size of 1.4mm, and then It is placed in a microwave oven with a microwave frequency of 2600MHz and a microwave power of 1400W for microwave treatment, and the treatment time is 7 minutes;

[0025] 2) Enzymolysis

[0026] Put the peony seed powder for oil obtained in step 1) into a reaction kettle, add 15 times the weight of deionized water to prepare a suspension of peony seed powder for oil, ultrasonically treat it for 85 minutes, and adjust the pH to 9.0 with an industrial compound base. Add alkaline protease to carry out enzymolysis reaction under the con...

Embodiment 2

[0033] A processing method for improving the oil yield of peony for oil, comprising the steps of:

[0034] 1) Microwave treatment

[0035] Pick the fully ripe purple-spotted peony fruits that have been removed from the soil, dry them in a dry and ventilated place for 4.5 days, beat the fruits to make the peony seeds fall off naturally, collect the fallen peony seeds, crush them into peony seed powder for oil with a particle size of 1.5mm, and then It is placed in a microwave oven with a microwave frequency of 2600MHz and a microwave power of 1400W for microwave treatment, and the treatment time is 7 minutes;

[0036] 2) Enzymolysis

[0037] Put the peony seed powder for oil obtained in step 1) into a reaction kettle, add 16 times the weight of deionized water to prepare a suspension of peony seed powder for oil, ultrasonically treat it for 90 minutes, and adjust the pH to 9.5 with an industrial compound base. Add alkaline protease to carry out enzymolysis reaction under the ...

Embodiment 3

[0044] A processing method for improving the oil yield of peony for oil, comprising the steps of:

[0045] 1) Microwave treatment

[0046] Pick the fully ripe purple-spotted peony fruits that have been removed from the soil, dry them in a dry and ventilated place for 5 days, beat the fruits to make the peony seeds fall off naturally, collect the fallen peony seeds, crush them into peony seed powder for oil with a particle size of 1.6mm, and then It is placed in a microwave oven with a microwave frequency of 2600MHz and a microwave power of 1400W for microwave treatment, and the treatment time is 8 minutes;

[0047] 2) Enzymolysis

[0048] The peony seed powder for oil obtained in step 1) is placed in a reaction kettle, and 18 times the weight of deionized water is added to form a suspension of peony seed powder for oil, which is ultrasonically treated for 95 minutes, and the pH is adjusted to 10.3 with an industrial compound base. Add alkaline protease to carry out enzymolys...

Abstract

The invention discloses a processing method for increasing the oil extraction rate of paeonia suffruticosa Andr, and belongs to the technical field of edible oil processing. Oil of the paeonia suffruticosa Andr is extracted by the four steps of 1) microwave processing, 2) enzymolysis, 3) centrifugal extraction and 4) demulsification oil generation. The paeonia suffruticosa Andr is subjected to microwave processing, and the processing method has the advantages of reaction promoting high efficiency and strong selectivity, simplicity and convenience in operation, fewer by-products, high yield, easiness in product purification and the like; the oil extraction rate of the paeonia suffruticosa Andr can be remarkably increased, the oil of the paeonia suffruticosa Andr with high oil content can be maximally extracted by the processing method, the oil extraction rate is 45%-50% and is increased by 18-30 percentage points, and economic benefits are improved.

Description

technical field [0001] The invention belongs to the technical field of edible oil processing, and in particular relates to a processing method for improving the oil yield of peony for oil. Background technique [0002] At this stage, due to domestic production restrictions and a surge in crushing volume, China's oilseed crushing raw materials are heavily dependent on imports. At present, the annual import of soybeans and rapeseeds has reached 60 million tons, with an import dependence of more than 80%. As a national strategic industry, it has far exceeded the national level. The red line of strategic security is equivalent to importing 400 million mu of soybean planting area every year. Therefore, we are in urgent need of a new oil crop to meet the large demand for oil in our country. [0003] Peony for oil (Paeonia suffruticosa Andr) is a shrub plant. The wild peony is mainly distributed in Gansu Province, Sichuan Province, and northern Yunnan. Currently, there are only t...
